Toribash graphics are messed up

[crazyfuturamanoob]

Toribash works well otherwise, but there are ugly stripes in the background, instead of blue sky.

Without shaders there aren't any stripes, but I absolutely can't play without them.


Graphics card:
NVIDIA GeForce 8600M GS, up to 1791Mb TurboCache
With NVIDIA accelerated graphics driver version 177


Any solution?

Give driver 180.xx a try.

Give driver 180.xx a try.

I removed 177 and installed 180 with synaptic but 180 doesn't show up in Hardware Drivers dialog.

Edit: Reboot, and 180 got automatically enabled. Drivers OK

But the ugly stripes still remain :(
